Detailed Description
template<typename T>
class sensesp::TimeCounter< T >
class sensesp::TimeCounter< T >
A transform that outputs the duration of the input value being true or non-null.
The main use case for this transform is to measure the total engine hours in a persistent way. The value is stored in the flash drive whenever the input state changes (the engine is turned on or off).
- Template Parameters
-
T The type of the input value. Must be castable to a boolean.

Deserializes the current object data from a JsonObject.
Reimplemented from sensesp::Serializable.
Definition at line 68 of file time_counter.h.
◆ set()
template<typename T>

Used to set an input of this consumer. It is called automatically by a ValueProducer but can also be called manually.
- Parameters
-
new_value the value of the input
